ECMT - Invalid column name <AX field>

When receiving the error for Invalid column name ‘<AX field>’ the Workflow item will not be kicked off even with a correctly FLAGGED DOCUMENT.

The error would show up like this:

Error Processing Document Kickoff for Workflow ‘AP-Invoices'. SourceDocument ID: Setting integration doc field : STATUS to : NEW :
Invalid column name ‘<AX Field Name 1>'.
Invalid column name '<AX Field Name 2>’.
Invalid column name '<AX Field Name 3>’.
Invalid column name '<AX Field Name 4>'.

Error Creating New Workitem :
Invalid column name '<AX Field Name 1>'.
Invalid column name '<AX Field Name 2>'.
Invalid column name '<AX Field Name 3>'.
Invalid column name '<AX Field Name 4>'.

This can be solved by checking if the table schema for the Workflow and checking if the columns needed are being created.
